To help move along the event, and utilize players time effectively I would have Loser Racks, winner breaks.
Like you mentioned, the 9 on the spot, has gotten rid of massive break and run packages. and made play much more fair.
In loser breaks, the class and etiquette of each player can be shown in a much better light either way....and SPEED UP PLAY.
Also, I would highly consider the of use wooden racks as they create a wonderful sound of play, and like the Willards event at Pheasant Run IL they were embossed and players could sign em for the buyers and sellers.
These wooden racks, were made by a good friend of Vivian V. in TX and, were top notch. That additional' 'sound'' of play, is almost as nice as hearing the ball slapping against the back of a Gold Crown Pocket.
Here's why loser should rack, ''especially if they are Drop pockets''. Both players are seen (in the public eye), working together during play to assist and roll balls down table and interact. When your racking, your basically remembering what you did wrong/or not/making sure they are tight, and when your breaking, your doing the same but from the winners perspective and your prepping for breaking while your opponent is doing his job. I wouldn't be surprised if all matches ran at least 20-30 minutes quicker that the rack your own. Only next best thing is having refs/rack at each table, and we know that's not possible now.
With the increase in entry fees and overall costs, the caliber of players at this event is world class, therefore in the players meeting DEMAND that they act like true pros and give your opponent a rack as good as you would for yourself. It's time to stop babysitting adults until there is a ref at each table. You could also tell the players that constantly complain about bad racks, that if it keeps up, you can take a game away if needed for unsportsmanlike conduct....that's what rack mechanics are, cheaters plain and simple, they need to GO.
